The STM810SWX6F from STMicroelectronics is a highly reliable, precision microprocessor (μP) reset circuit device that provides a significant level of protection for embedded systems. This advanced component is designed to monitor the supply voltage of microprocessors, ensuring that the system resets accurately during power-up, power-down, and brown-out conditions.

Key Features

• Supply Voltage Monitoring: The STM810SWX6F actively monitors the V<sub>CC for under-voltage conditions. When the supply voltage drops below the reset threshold level, the reset output is asserted (driven low) to reset the μP.
• Reset Timeout: After the supply voltage returns above the reset threshold, the device maintains the reset condition for a preset timeout period, ensuring the μP has adequate time for stabilization.
• Low Power Consumption: Designed for energy-sensitive applications, this component boasts an extremely low power consumption, contributing to the overall efficiency of the system it is incorporated into.
• High Accuracy: The reset threshold voltage is highly precise, providing reliable reset activation and deactivation, which is crucial for maintaining system integrity.
• Compact Package: The STM810SWX6F comes in a small SOT-23 package, making it ideal for space-constrained applications.

Applications

This reset circuit is versatile and can be used in a wide array of applications where reliable system reset functionality is critical. It is particularly well-suited for:

• Computers and servers
• Embedded systems
• Portable/Battery-powered devices
• Industrial equipment
• Consumer electronics

The STM810SWX6F is a testament to STMicroelectronics' commitment to providing advanced circuit protection solutions that enhance the reliability and performance of electronic systems. With its precision voltage monitoring and low power consumption, this reset circuit is an essential component for any design requiring robust μP supervision.
